The first funny number: If a 1 is placed after this five-digit number, the result is triple the number you'd get by putting the 1 in front. The second funny number: It's the second-smallest odd number greater than 1 that's a perfect cube and also a perfect square. The third funny number is the smallest with the property that if any prime between 10 and 20 is divided into it, the remainder is 1. What's the exact product of the three funny numbers?

It isn't indeed. And English is my second language, so all this time I've thought that it meant the same thing when applied to division.

So, BobbyGo has it then...

Unless superprismatic is right.  I didn't even consider that the third number might be less than the primes instead of greater.
